San Francisco Bay Area Overview

• Seven million residents
• 2nd most congested region in

US.

• More than 4.6 million cars
• 20,000 miles of local streets

and roads

• 1,420 miles of highway
• 450 miles of carpool lanes
• 8 toll bridges
• 28+ transit agencies
• Extensive ITS infrastructure

3

SF Bay Area State Highway ITS Infrastructure

4

• 2,500 traffic detection

stations

• 140 changeable message

signs

• 390 cameras (traffic

monitoring & incident management)

• 380 ramp metering systems
• Regional TMC
• Call boxes, Freeway Service Patrol, 511 traveler information
• Express Lanes & Integrated Corridor Management

Performance: Freeway Sensors

• Statewide sensors reliability goal: 70%
• For the past year, only ~50% of sensors installed in the

roadway have been functional

Suspected Errors

• Sept. 2011
• Sept. 2012

Ctlr Down (22 %) Other Errors (3 %) Card Off (70 %) High Value (5 %)

• “…dealing with

preservation shortfalls has an exponential fiscal impact (the less you do today, the more it will cost you tomorrow).” Caltrans Program Review—July 2012.

TMS Governance Principles

Performance

• Define performance targets to optimize operations.
• Achieve TMS operational benefits across multiple systems and programs.

Decision Making

• Adopt a performance management approach.
• Streamline TMS decision‐making and prioritization.
• Ensure accountability and transparency.
• Secure a management stake.

Resources

• Strategically manage the system within the resources available.
• Leverage regional contribution to secure funding commitment from state.

11

Shared TMS Vision

A regional, integrated Bay Area freeway network that provides a safe and reliable travel experience for the region’s travelers. To achieve this we will:

• Actively manage our network infrastructure and assets;
• Be responsive to our customers’ need for a consistent

travel experience across the region;

• Place a high priority on the safety and security needs of
• ur travelers and network infrastructure investments;

and

• Utilize our fiscal and staff resources in a manner that is

effective and fiscally responsible.

TMS Needs Assessment

Assessment is underway to identify common field equipment issues and resolution strategies:

• Copper wire theft
• Software repairs
• Equipment failure rates
• Trend analysis

16

Analysis of the type, frequency and cost of repairs will inform future resource requests

Performance: CCTV Cameras

• Upgraded 390 CCTV cameras
• 186 are operational
• Communication infrastructure

needs investment

Performance: Ramp Metering

To be expanded from 380 locations (40% of system) to 500 locations (53% of the system) by 2015

18

Performance: Changeable Message Signs

• 140 CMS ‐ 33 with Travel Times
• Caltrans calculates the CMS travel

times

• 511 conducts performance

monitoring of CMS travel times

• Due to advances in technology,

511 uses GPS probe‐based data, provided by INRIX, at lower cost and greater coverage
